A national survey on assessment of knowledge, perceptions, practice, and barriers among hospital pharmacists towards medication reconciliation in United Arab Emirates

Medication reconciliation (MedRec) helps prevent medication errors. This cross-sectional, nationwide study assessed the knowledge, perceptions, practice, and barriers toward MedRec amongst hospital pharmacy practitioners in the United Arab Emirates. A total of 342 conveniently chosen stratified hospital pharmacists responded to the online survey (88.6% response rate). Mann–Whitney U test and Kruskal–Wallis test were applied at alpha = 0.05 and post hoc analysis was performed using Bonferroni test. The overall median knowledge score was 9/12 with IQR (9–11) with higher levels among clinical pharmacists (p < 0.001) and previously trained pharmacists (p < 0.001). Of the respondents, 35.09% (n = 120) practiced MedRec for fewer than five patients per week despite having a strong perception of their role in this process. The overall median perception score was 32.5/35 IQR (28–35) with higher scores among clinical pharmacists (p < 0.001) and those who attended previous training or workshops (p < 0.001). The median barrier score was 24/30 with an IQR (21–25), where lack of training and knowledge were the most common barriers. Results showed that pharmacists who did not attend previous training or workshops on MedRec had higher barrier levels than those who attended (p = 0.012). This study emphasizes the significance of tackling knowledge gaps, aligning perceptions with practice, and suggesting educational interventions.

The negative consequences of medication errors are acknowledged as one of the biggest threats to the global healthcare system 1,2 .Statistics from the United States (US) showed that more than 250,000 patients die every year due to medication errors 3 .In addition, medication errors lead to significant human suffering and economic losses.Multiple strategies have been implemented with varying success and undoubtedly it is possible to reduce or even prevent medication errors by developing more effective healthcare systems and implementing patient safety initiatives 4 .One such initiative to minimize medication errors is medication reconciliation (MedRec), which is acknowledged as preventing possible medication errors and enhancing the accuracy of medication lists 5 .In definition, MedRec is "the process of creating the most accurate list possible of all medications a patient is taking-including drug name, dosage, frequency, and route-and comparing that list against the physician's admission, transfer, and/or discharge orders, to provide correct medications to the patient at all transition points within the hospital" 6 .
Medication reconciliation is performed by physicians, nurses, and pharmacists.It is well reported that pharmacists can have a significant impact on enhancing the safety of medication by contributing to the MedRec process and correcting any medication discrepancies 7 .Many published data show that pharmacists are specially prepared to lead interdisciplinary efforts and build an efficient MedRec process in hospitals and across health www.nature.com/scientificreports/

Sample size calculation
A sample size of 385 was determined using Cochran's formula 23 .In this study, the population size consisted of the total number of pharmacists working in UAE hospitals.There are no published data on the total number of pharmacists working in UAE hospitals specifically.However, based on the statistics in 2020, there are 11,153 total pharmacists working in both community and hospital pharmacies in the UAE (5518 males and 5635 females) 24 and some publications mention about 1300 pharmacists working in community pharmacies 25 .By estimating the total number of hospital pharmacists in UAE, it was calculated as 9853 pharmacists.The sample size is determined using the Cochran formula as outlined below: For the calculation of the required sample size (n 0 ), the following parameters are used: Z, which is set at 1.96 to achieve a 95% confidence interval (CI), and a marginal error of 0.05.The expected proportion (p) is assumed to be 50%, and precision (e) is set at 5%.Consequently, we obtained ((1.96) 2 (0.5) (0.5))/(0.05) 2 = 385.

Sampling method
In this research, stratified convenient sampling technique was used in collecting data.The population is hospital pharmacists in UAE (N = 9853).The 'working Emirate' was selected as stratification in this study, so there were seven strata.The next step required listing the population which means having an access to all hospital pharmacists' records working in UAE.In fact, the researchers did not have access to these records, instead, they listed the details of all hospitals in UAE and this was taken from the yellow pages.The hospital details were added to an excel sheet, then the population was listed according to the chosen stratification.For this step, a consecutive number was given to each hospital in each stratum.As a result, authors arrived at seven lists as the following: Abu-Dhabi hospitals, Dubai hospitals, Sharjah hospitals, Ajman hospitals, Ras Al-Khaima hospitals, Fujairah hospitals, and Umm Al-Qawain hospitals.
The following step was to choose the sample size (n) which was calculated using Cochran formula (n = 385).Then, the proportionate stratification was calculated by multiplying the intended sample size (n) by the proportion of units within each stratum, therefore, the number of hospital pharmacists in each Emirate has to be known.Since this number is unknown, the researchers tried to figure it out by doing the following: first, the published data about the percentage of the UAE population in each Emirate was searched 26 .Then, the total number of hospital pharmacists in UAE (9853) was multiplied by the proportion of the population in each Emirate.The resulted number for each Emirate yielded a summation of 7853.Calculation was made to reach this summation to 9853 and the number of hospital pharmacists in each Emirate was defined as shown in Table 1.
The last step was applying a simple random sampling technique for the selection of the listed hospitals.Once the hospitals had been selected, their affiliated pharmacists were approached via the LinkedIn platform.

Data collection instrument
The study questionnaire had five parts; 1. Demography, 2. knowledge (self-developed), 3. perception, 4. practice and 5. barriers (all later three adapted from a Jordanian study) 27 after obtaining permission.A thorough literature review was done to develop knowledge questions with extensive discussions between the co-authors [28][29][30][31] .

Knowledge part of the questionnaire
The knowledge questions are built based on four main domains (What, Who, Why and How) as the following: What is MedRec, 3 questions; objectives of MedRec, 2 questions; Who can do MedRec, 2 questions and How to do MedRec, 5 questions.The knowledge about MedRec was assessed by asking the participants 12 multiplechoice questions.The researchers preferred to ask multiple choice questions rather than "Yes", "No" questions to assess the real knowledge of participants about this comprehensive process.
The content validation was done by three experts.The panel of experts comprised two clinical pharmacists holding Board Certification as Pharmacotherapy Specialists in the UAE and an academician in the University of www.nature.com/scientificreports/Central Lancashire in UK.Their suggestions and comments were considered in updating the knowledge questions as the following: adding "I do not know" option to all knowledge questions and changing the word "correct" to "appropriate" in one of the answer responses of question 9.
After that, face validity was done by distributing the questionnaire to five hospital pharmacists working in different Emirates.They were requested to fill out the questionnaire and give their feedback on its clarity, relevance, appropriateness, and adequacy.Their comments were positive towards the questions and the questionnaire was finalized with 12 items.

Assembly of the final tool
The final study tool had five components.In Part I, there were nine questions related to participants' sociodemographic information, followed by five general questions.Part II involved a knowledge assessment that encompassed 12 items and was evaluated through multiple-choice questions.For Part III, the current practice of hospital pharmacists on MedRec was evaluated by asking four questions.In Part IV, the focus was on pharmacists' perceptions of MedRec, which included seven items.Pharmacists were requested to indicate their level of agreement using a 5-point Likert scale, ranging from 5 for "strongly agree" to 1 for "strongly disagree".Part V consisted of six questions related to Pharmacists' perceived barriers towards MedRec where a 5-point Likert scale was used.

Knowledge scoring
The 12 knowledge questions about MedRec were determined by asking multiple-choice questions with only one correct answer.The phrase "I do not know" was added as an option to select for all knowledge questions.The correct answer scored (1) while the incorrect answers including "I do not know" answer scored (0.0).

Practice scoring
Pharmacists' practice was assessed by asking three questions in a form of "Yes", and "No" questions while the fourth question was a multiple-choice question with four available options.

Data collection
The pharmacists were accessed via the LinkedIn platform where screening of their affiliation and designation was done by the researcher and those who are eligible for the study received the participants' information sheet and the consent form.Those willing to participate and signed the consent form received a google link to fill in by answering the survey questions.

Pilot testing
A pilot study was conducted during 1st March till 15th March 2023 by distributing the questionnaire to 17 hospital pharmacists whose data were subsequently omitted from the final analysis of the study.The purpose of the pilot study was to check the feasibility of the study and assess the reliability of the study tool.Using SPSS software version 28.0, Cronbach's alpha (α) was computed to evaluate internal consistency and scale reliability.The calculated Cronbach's alpha (α) value was 0.781, which means that the items have relatively high internal consistency 32 .

Data analysis
The data collected through the Google survey was imported into IBM Statistical Package for the Social Sciences (SPSS) Version: 28.0.0.0 (190).Data were analyzed quantitatively using descriptive statistics (mean, standard deviation (SD), median, range, frequency and percentage) in addition to inferential statistics.Results of sociodemographic data in addition to training and practice questions were reported as frequencies and percentages.Results of perceptions and perceived barriers were described as the percentage of pharmacists who expressed varying degrees of agreement with each statement, ranging from strongly agree to strongly disagree.
All quantitative scales for knowledge, perception, and barriers are normalized on a 100-point scale from 0 to 100.The test of normality for knowledge, perception, and barriers scales was done using the Shapiro-Wilk normality test.Since all scales are not normally distributed (p value = 0.000), non-parametric tests are considered for relations.Mann and Whitney U test for comparing two independent groups (gender, country of graduation, clinical pharmacist and previous training on MedRec) whereas the Kruskal Wallis test was used when dealing with multiple independent groups, exceeding two (age, years of experience, education level, and working Emirate).For groups with significant relations, post hoc analysis was done using pairwise comparison test and Bonferroni was applied.The correlation of the main scales (total knowledge scale and total perception scale; total knowledge scale and total perception scale; total perception scale and total barriers scale) was done using Spearman's rho test.A moderate correlation was considered if the correlation coefficient is between ± 0.4 to ± 0.6 while it was considered weak if the correlation coefficient is between ± 0.1 and ± 0.3 33 .Throughout the analysis, a p-value of < 0.05 was considered statistically significant.

Results
Hospital pharmacists included in the study are working in the seven Emirates: Abu Dhabi, Dubai, Sharjah, Ajman, Ras AlKhaima, Um Al-Qawain and Fujairah.The survey was distributed to 386 hospital pharmacists working in the UAE and of those, 342 filled out the questionnaire giving an overall response rate of 88.6%.The total number of participants was 88.8% of the calculated sample size.

Sociodemographic profile of participants
The socio-demographic characteristics of the participants are presented in Table 2. Participants were mostly females (54.7%) whereas the percentage of males was 45.3%.The mean age for the sample group is 31.38 with 95% CI between (30.75-31.94)while the mean years of experience is 5.47 with 95% CI between (5-6).Most of the participants are Bachelor's degree holders (54.7%) whereas (29.24%) are clinical pharmacists.Among the participants, 141 (41.20%) are working in outpatient pharmacies.www.nature.com/scientificreports/

Pharmacists' skills and training about medication reconciliation
More than 90% of the respondents stated they have enough skills to take the best possible medication history from patients.Similarly, the majority reported their confidence in having enough skills to apply MedRec during patients' transition of care (80.7%).When asked about their previous training or study on MedRec, more than half of the participants denied studying a related course in their university (52.92%) and four-fifths of participants agreed on the need for more training programs about MedRec (Table 3).

Pharmacists' knowledge about medication reconciliation
The overall median knowledge score was 9 with IQR (9-11) and the maximum possible knowledge score was 12.
The majority of participants could define MedRec correctly (81.9%); identify its goal (91.2%) and know which medications to ask during the process (86%).When focusing on the technique of conducting the process, the percentages of correct answers fluctuated as only 54.7% know that medication discrepancies can be intentional and unintentional and 58.5% understand how to achieve the "best possible medication history" while 66.4% are aware of which stage MedRec can be applied.Participants' correct, incorrect and "I do not know" responses to each knowledge question are shown in Table 4.

Pharmacists' current practice of MedRec
The current practice of MedRec was assessed by asking 4 questions.Most of the participants (83.33%) are aware if there is a MedRec policy in their hospital.The majority (72.51%) answered implementing MedRec is a part of their job description and they have to apply it to all admitted patients (74.56%).When asked "on average, for how many patients do you implement medication reconciliation in your pharmacy per week?", 35.09% selected less than 5 patients; 23.68% answered between 5 and 9 patients; 11.7% stated from 10 to 14 patients and 29.53% reported more than 15 patients (Table 5).www.nature.com/scientificreports/

Pharmacists' perception of medication reconciliation
The test of normality the for perception scale was not normally distributed with an overall median perception score was 32.5 IQR (28-35) and the maximum possible perception score is 35.The Perception of MedRec among hospital pharmacists was assessed by asking 7 questions and the results of each question are shown in Table 6.
The maximum number of participants (97.96%) perceived that pharmacists can help in assessing the appropriateness of medications for patients.

Pharmacists' perceived barriers on implementing medication reconciliation
Barrier scale was not normally distributed with an overall median barrier scale for all participants is 24 with IQR (21-25) and the maximum possible barrier score is 30.Pharmacists were asked 6 questions to identify the barriers that may render them from practicing MedRec.Table 7 shows participants' responses to each question.
A high agreement level among the majority of participants that the 6 listed barriers are obstacles that render them from implementing MedRec.

Correlations between MedRec knowledge, perception and barriers scales
Spearman rho rank correlation test was used to show the relationships between different scale (Table 8).There is a statistically highly significant of positive correlation with moderate strength between total knowledge scale and total perception scale (p value < 0.001).On the other hand, there is a significant negative correlation with weak strength between total knowledge scale and total barrier scale (p value = 0.036).

Influence of demographic factors on respondents' knowledge, perception and barriers
Demographic Factors that affect hospital pharmacists' knowledge of MedRec were evaluated using the Mann and Whitney U test (for 2 groups) and the Kruskal Wallis test (for > 2 groups).Post hoc analysis was done by applying Bonferroni test whenever there are significant relations between groups.www.nature.com/scientificreports/

Knowledge
The results showed that clinical pharmacists have better knowledge scores than non-clinical pharmacists as the p-value is highly significant (p value < 0.001), also those with master or pharm D and PhD qualifications showed a highly significant difference in their knowledge than bachelor holders (p value < 0.001).Moreover, pharmacists who took training on MedRec previously or studied a course in the university have higher knowledge compared to those who did not (p value < 0.001).Years of experience is also a factor that affects the knowledge of the participants as those with more experience (≥ 5-< 10; ≥ 10-< 15) have higher knowledge than those with fewer experience years (≥ 0-< 5), where the p value < 0.001.Similarly, the results indicate that as the age of participants increases, their knowledge also increases (p value < 0.001).On the other hand, gender, and country of graduation do not influence on knowledge (Tables 9, 10).Post hoc analysis using pairwise comparison showed a statistically significant difference in the total knowledge scores between the age group of [20 to below 30] and [30 to below 40] (p < 0.001), [20 to below 30] and [40 and above] (p = 0.004).There was also a statistically significant difference in the total knowledge scores between the years of experience [< 5 years] and [5-< 10 years] (p = 0.002), [< 5 years] and [≥ 10 years] (p < 0.001).A statistically significant difference was also noticed in the knowledge between the qualifications [bachelor] and [master or Pharm D] (p < 0.001), [bachelor] and [PhD] (p = 0.002).The test illustrates a statistically significant difference in the knowledge between the type of hospital [private non-teaching] and [government] (p < 0.001), [private  9, 10).Post hoc analysis using pairwise comparison shows a statistically significant difference in the perception between the age of [20 to below 30] and [30 to  The test shows a statistically significant difference in the perception between the type of hospitals [private nonteaching] and [private teaching] (p = 0.004), [semi-government] and [government] (p = 0.002), [semi-government] and [private teaching] (p < 0.001).Working Emirates is also a factor that affects the perception as the test shows a statistically significant difference in the perception between those working in Abu-Dhabi and Dubai Emirates (p < 0.001).

Barriers
Factors that have an impact on the participants' perceived barriers to implementing MedRec can be seen in Tables 9 and 10.Post hoc analysis using pairwise comparison showed a statistically significant difference in the barrier between the pharmacy site of work [outpatient pharmacy] and [pharmacy on duty] (p < 0.001).

Discussion
It is indisputable that reducing medication errors is a matter of concern for every healthcare system 34 .Different strategies have been proposed and implemented to overcome the threat of these errors 4 .MedRec is an important process that can detect medication discrepancies, minimize medication errors, and hence enhance safe medication use 5,35,36 .Although it is a shared responsibility of all healthcare providers, given pharmacists' expertise in medicines, pharmacist-led medicines reconciliation should be recognized for its accuracy in completing www.nature.com/scientificreports/patients' medication histories, determining and reconciling medication discrepancies, and suggesting the necessary interventions [37][38][39] .
The UAE consists of seven Emirates wherein its healthcare system has witnessed rapid growth in its capacity and quality 40 .The Federal Ministry of Health (MOH) is regulating the health system in the Northern Emirates in addition to regulating the high-level functions in all Emirates.Abu-Dhabi and Dubai Emirates have their own health regulations 41 .It has been reported that the quality and cost of services vary between Emirates as less development is realized in Northern Emirates compared to Dubai and AbuDhabi 42 .There are no studies conducted in the UAE to measure the hospital pharmacist's knowledge, practice and perceptions towards MedRec and to address the main barriers that may render them to practice it, hence this study was performed.
The majority of respondents are confident that they have enough skills to apply MedRec and take "the best possible medication history" from the patients in spite of denying studying a related course in the university.More than half of the pharmacists received a training or attending a workshop related to MedRec and this could explain the high confident level expressed on their skills.Moreover, this study included clinical pharmacists and pharmacists with high qualifications which could increase the confident level.However, the majority of participants admitted that they need more training programs related to MedRec.Our results are in line with Katoue et al. study in Kuwait which indicates that 90% of their hospital pharmacists attended formal training on MedRec while there is a need for more training to practice this process 43 .The same researchers realized this need and they developed a simulation-based workshop to hospital pharmacists in Kuwait 44 .The necessity to train the pharmacists have been recognized globally and different associations published MedRec toolkits that can be utilized to train pharmacists and other healthcare providers [45][46][47] .
The majority of participants have to implement MedRec to all admitted patients as it is part of their job descriptions.Surprisingly, although most of respondents are aware about MedRec policy in their hospitals, almost one-third of them implemented MedRec for less than five patients per week.These contrary results could be justified by saying that addressing policies and job descriptions are not enough to obligate pharmacists to practice as there could be some barriers that need to be investigated to resolve this mystery.This study revealed that limited role of pharmacists is witnessed in practicing MedRec.These results are consistent with a Jordanian study which contributed lack of awareness among hospital pharmacists to their modest role in the process 27 .
Results of this study show that participants know basic information related to MedRec like its definition and objectives but faced some difficulties in answering "How" questions.This could be due to the fact that majority of participants didn't study about MedRec in the university.When compared to other studies conducted, low awareness level of the concepts of MedRec and medication safety were addressed 16,48 .Furthermore, a recent published Nigerian study evaluated hospital pharmacists' knowledge on MedRec as "poor" 49 whereas a mixed method designed study conducted in US reported lack of knowledge among healthcare providers about the process of MedRec 50 .Interestingly, Lemay J et al. reported higher knowledge of MedRec among hospital pharmacists compared to physicians 21 .Although all the participants in the current study are pharmacists, yet when asked who is the most suitable healthcare provider to take "the best possible medication history", the minority answered "the pharmacist" while the majority selected "All of the above choice" which include physicians, pharmacists and nurses.MedRec process requires collaboration of interdisciplinary team and every healthcare provider can indeed take part in it, but when it comes to medication history, pharmacists are best suited due to their unique expertise in medications 30,51,52 .A Belgium study was done to compare medication histories acquired by pharmacists versus physicians in emergency department found that pharmacists took medication histories more accurately than physicians and they supported pharmacist role in this step 53 .
The current study revealed that clinical pharmacists, previously trained pharmacists, experienced pharmacists and those with higher educational levels have significantly better knowledge about MedRec than other groups.In contrary, gender; country of graduation and working Emirates did not influence participants' knowledge.This conforms to the study done by Aje et al., who reported qualification but not gender influenced pharmacists' knowledge on MedRec 49 .These results confirm that the current practicing pharmacists had graduated from curricula that were not focused on clinical aspects.They also highlight the privilege of completing the educational level and being specialized in clinical pharmacy field which can provide the essential knowledge to deliver services that can improve patients' clinical outcomes.Besides, as knowledge is cumulative process, it can be consolidated by having more experience where there are more interactions with patients in the daily practice.
The overall perception level about MedRec implementation among participants is very high.Most of the participants agreed that this service should be provided to all patients.They also perceived that they can be integrated with other healthcare providers, providing support and advice for medical team as well as for patients and their families.These results are compatible with many published studies that showed high perception level among pharmacists towards MedRec process 20,21,27 .Factors that significantly influenced pharmacists' perception level are years of experience, age, qualifications, clinical pharmacy education, training on MedRec, and working Emirate.Again, gender and country of graduation did not have an effect on pharmacists' perception level.A study conducted in Jordan revealed that postgraduate and experienced pharmacists possess higher perception level than others 27 .
Many factors can affect the practice of MedRec.In this study, the vast majority of participants agreed on that the 6 listed items are barriers that prevent them from practicing MedRec.The main barrier that received the highest agreement level is lack of training, followed by lack of knowledge.Additional barriers include: lack of corporation and communication among healthcare providers, lack of time and lack of access to patients' medical records.These results are line with what had been mentioned in the literature, for instance, several studies conducted in GCC countries addressed the obstacles towards implementing this process and they concluded that lack of knowledge, lack of policy, lack of time, difficulties in accessing patients' files, lack of agreement among healthcare providers, patients' barriers are the main obstacles towards practicing MedRec 43,54,55 .Other countries including US 50 , Brazil 56 , and Ireland 57 reported similar barriers.The current study illustrates that the barriers experienced by the pharmacists are influenced by their educational level, pharmacy working sites and if they are previously trained.Identifying the obstacles will aid in improving the practice by suggesting certain recommendations.Many researchers studied the key factors to enhance the practice of MedRec and they concluded that providing ongoing education and training to healthcare professionals, fostering an effective communication among them, their propensity for change and support from management are the key elements to improve the practice [58][59][60] .Additional factors recorded in the literature include using standardized tools in MedRec process and knowing the exact duties and tasks for each healthcare provider [61][62][63] .It is important to highlight the importance of incorporating interprofessional education in the universities besides focusing on strategies to improve patient safety in training and theoretical courses.

Strengths and limitations of the study
This study presents a comprehensive work assessing the role of pharmacists in MedRec in UAE and addressing important aspects of patient safety and healthcare quality.The study addresses an existing gap in the literature by focusing on the involvement of pharmacists in MedRec in UAE.It achieves this by evaluating their knowledge, current practices, and perceptions-a domain that has received limited research attention.It also sheds light on the challenges faced by pharmacists and emphasizes the potential for improving patient safety through structured systems and defined roles.To the best of authors' knowledge, this research is the first of its nature conducted in UAE to assess hospital pharmacists' knowledge, practice, perception, and perceived barriers towards implementing MedRec where hospital management and other concerned authorities can extract useful information from this work.Additionally, it is a nationwide study that includes hospital pharmacists for all Emirates and a stratified sampling method was used to assure participants proportional to the overall population.
Besides these strong points, this study has some limitations which could be considered in future research.The study used a self-administered questionnaire that has a close-ended question that limited the responses to select from the available options where some important aspects could be missed.For instance, only six barriers are listed to the participants and there could be some other obstacles that are unaddressed.Moreover, this study included diverse hospital settings within the healthcare system in UAE which could make the inference on the current practice of MedRec quite difficult.Also, the researchers did not succeed to achieve the required sample size as only 88.8% had been reached.Furthermore, the hospital pharmacists were approached through their individual pages in LinkedIn platform while there could be other pharmacists who do not use this platform and they are eligible to be included in the study.

Recommendations
The study recommends that providing hospital pharmacists with comprehensive training and educational workshops on MedRec is essential for improving patient safety and the overall quality of healthcare.The focus of these training courses should be on the technique and the steps of MedRec to perform it accurately and efficiently.It also emphasizes continuous learning and interdisciplinary collaboration.Furthermore, it suggests incorporating more hands-on training on MedRec in pharmacy curricula.This will help students to develop the necessary skills and confidence to perform MedRec accurately and efficiently when they are practiced pharmacists.
Positively, the perception of pharmacists and their confidence level in leading the process is very high in this study indicating a strong commitment to be actively involved in this process.The more confident pharmacists are more likely to take proactive roles and this suggests having clear and well-defined hospital policies that outline the roles, responsibilities, and expectations for pharmacists in MedRec.Clear policies can also enhance collaboration among healthcare team members, including pharmacists, nurses, and physicians as this collaboration is essential for accurate and comprehensive MedRec.
As the study design is quantitative in nature, using qualitative or mixed-method research designs is recommended in future research.This can provide a deeper understanding and better recommendations for improving MedRec practices among pharmacists.

Conclusions
As a conclusion, this study revealed that pharmacists expressed different levels of knowledge but showed a positive perception and willingness to practice MedRec.While the role of pharmacists in MedRec process is recognized worldwide, it is important to establish a system that defines their roles in UAE hospitals.The Department of Health Services in UAE has adopted number of plans to enhance medication therapy management services, however, pharmacists' expanding duties and pharmaceutical care are not really ideal from a practical standpoint.Moreover, hospital pharmacists have highlighted several barriers to practicing MedRec, such as a lack of knowledge and training in this field.It is crucial to offer a continuing education program using various educational approaches to enhance MedRec practice among hospital pharmacists. https://doi.org/10.1038/s41598-024-64605-4www.nature.com/scientificreports/ below 40] (p < 0.001), [20 to below 30] and [40 and above] (p = 0.002).The test also shows a statistically significant difference in the perception between the years of experience [< 5 years] and [5-< 10 years] (p = 0.002), [< 5 years] and [≥ 10 years] (p < 0.001).A statistically significant difference is presented between perception and qualification [bachelor] and [master or Pharm D] (p < 0.001).
